In modern constructions of cream' separators attempts have been made to'obtain the bestI possible lubrication, and it has pref# erably been soarranged that the lubrication is made automatically from one oilreceiver. Difficulties have, however, been experienced in obtaining athorough oiling of the neckbearing inasmuch as the oil has 'to be liftedfrom the oil .receiver to the neck bearing, and on account of theconsiderable distance between thesetWo the oil frequently fails toksatisfactorily reach the neck-bearing.

' The fobject of the present invention is to overcome some diicultiesand provide 'for etiicient lubrication of the neck-bearing.

The invention consists in providing means for conveying an ample supplyof lubricant to an upper neck-bearin means -for facilitating the assageof t e lubricant therethrough and) means for returning the lubricant tothe source of supply. The invention further consists in errang in1r onthe worm wheel or on any other reo ving part certain agitators whichcause 25 the oil in the oil receiver to s lash to quite considerableheights; the oil will thus safely reach the neck-bearing and may bymeans of spiral groo'ves be circulated therethrough..

The invention further renders it possible to ascertain that the oil isproperly circulated through the neck-bearing inasmuch as the oil afterhaving passed through the neckbearing is arranged to flow to the outsideof '.f leaves the spindle bearing in order to return the machine and itmay be so arranged that the amount of oil pasing through may becontrolled after it has passed through the bearing.

The invention further makes it possible to adjust the air pressure orsuction round the .neck-bearing or atthe point where the oil to the oilbath.

The accompanyingdrawing shows by way of example a convenient embodimentof the' invention.l

In theconstructlon shown 1n the drawlng A 1s a separator frame and B 1san oil container situated in the bottom of a compart ment containing thedriving gear.

C is a. worm wheel for driving the spindle, said worin wheel beingfitted with agitators or throwers D adapted during revolution of thewheel to eiectually throw oil to the upper part of the casing.

E is a vertical separator spindlepassing through the neck-bearing Fwhich is fitted .at its lower end with a tray or dish collector G fromwhic'h the oil passes into an annular chamber Gr1 surrounding the.bottom of the bearing and from which are carried one or more spiralgrooves H 'formed in the bearing material and adapted during revolutionof the spindle to circulate the oil in an up- Ward direction through thebearing. 4

The oil flowing from the top of ,the bearing is carried by a passageIland pipe I outside the casingr to a positionwhere it may i -i,1,6os,4'13 ori-uca.

be conveniently observed and from the pipe I the oil`iiows into a returnconduit K which conducts the oil back into the container B in the bottomof the leasing.

By means .of the air-pipe itis possible. -1 y to adjust the air-pressureor suction near the spindle bearing and this-is done vby pressing thepipe further into the bowl house O or by I bringing itoutwards so that ashorter piece of pi )e protrudes into the bowl, house O. There y it ispossible to regulate the oilfiow so that the oil will not be sucked intothe bowl house O and also to prevent an airpressure which will tendto'ham'per the oilv flow. The pipe may conveniently have ai The wormwheel revolves inthe direction of the'arow and, assisted by theAagitators D, throws the oil from the receiver up to the top of thecasing where it is caught by the tray G, the oil then passing throughthebearing and returning to the casing as here- 'i inbefore described.

Having now particularly described and ascertained the nature of the saidinvention and in what manner same is to be performed,

I declare that what I claim is 1. In alubricating device ofthe characterdescribed, a casing havin an oil container in its lower part and a owlhouse in its upper part, a revoluble `vertical spindle mounted in thecasing, the means for mounting said spindle including a vertical bearingat the bottom of said bowl house, said bowl house being formed toproduce an inner chamber surrounding the upper end portion named pipedischarges said pipes being spaced of saidzvbearing, means for causingoil to pass upwardly from said 4oil container through said bearing andinto said inner in itslower partand a bowl house at its uper end, arevoluble vertical shaft mounted ,1n the casing, a chamber at the innerendof the upper bearing of the shaft, a splashing device in the casingfor throwing the oil into said chamber, means for causing the oil topass upward through said bearing, a chamber in t e bowl house andsurroun ing the outer end of said upper bearing, a pipe extending fromthe last named chamber out, through the casing, and a pipe extendinginto the casing and linto which the rst the adjacent ends of apart toafford visible indication of the flow ornon-iiow of oil' through saidfirst named pipe.` Y

v3. In a device of the character described, a casing having an oilchamber. in its lower part, a rotary vertical spindle mounted in thecasing, the means for mounting said spindle including a vertical bearingat'the upper end of the casing, means for splashing oil from the lowerpart of the casing to said bearing, said bearing and said spindle beingcooperativey formed to cause oil -to pass through said bearing, andmeans comprising two disconnected parts extending outside of the casingfor returning oil which passes through the bearing. back into saidcasing and for affording vvisible indication as to whether or not oil ispassing through said return means. i

4. In a lubricating device of the character described, a-casing ha'vinvra bowl'house in its upper part, a revolublie vertical spindle extendingthrough the bottom of the bowl house centrally 1- of the latter, saidbowl house having an inner chamber surrounding said spindle, and an airpipe extending throug `the bottom of the bowl house into the spacewithin the bowl house outwardly of the inner chamber, the inner' end ofsaid air tube terminating above the level ofthe bottom of the bowl houseand below the level of the edge ofY said inner chamber and-said air pipeb eing movable longitudinally to vary within limits the length of theportion of the air pipe that extends into the bowl house.
